Need some advice on 1st gurrila attempt

Ok so I am planning on doing a guerrilla grow on some secluded, well forested land near my place. I am not worried about the location I have scoped it twice and it seems stellar. I have the seeds ordered from Amsterdam Marijuana seeds, and it is there 'happy outdoor mix'. After ordering I researched AMS and saw that I probably shouldn't have ordered from them.

I'm planning on mixing each radius where I'm planning on planting with existing soil, good soil, and fertilizer. Since I am not likely going to be able to go and water these outdoor plants I am going to try to find a gully or a place with descent water supply. I am considering adding water retaining crystals to the mix as well because where I live we don't get that much rain usually(Nor too little either). Good idea or not much point you think?

Here are some questions of mine.
I live in Southern Canada, so our growing season is limited. It basically is june 1st- October 1st give or take a couple weeks. I am planning on germinating the seeds as soon as i get them. Should I start the plants indoors and then carefully bring them to the site or should I just plant the germinated seeded in the forest?
If indoors what would be the best light to dark ratio? I have some good lumen/quality fluorescent bulbs so im not worried about the lighting.

ftw I am going to plant 20-25 seeds with hopes of having at least 10 females.

Any further advice/ constructive criticism?

Thanks.

Definitely start indoors with 24 hours of light for 2 weeks. Then drop it down to 18/6 or plant in forest depending on what u think they can handle

Start them in party cups or the styrafoam coffee cups. Poke holes in the bottom of the cup and after the seeds germinate then place them in the soil and make sure you use bottled water to start off the seeds otherwise you need to go buy a ph balance.

It would defintely be worth trying. When I grew outdoors ending up with 5 good females out of 20 plants was average. Had more trouble with deer, rabbits and bugs then watering. I checked my plants religiously once a week. If I had 200.00 in seeds invested in seeds thier is noway I couldn't at least check on them.
